Nail Polish Mavens - Help Me Out?!

Nail Polish Mavens - Help Me Out?!

So today I went to the doctors since I've had painful bumps around my nails which appear and reappear randomly throughout the year. I've had this for about...three years. Yes, I've been to the doctor before but he gave me some useless cream which did absolutely nothing...then told me to keep using it when I went back...then booked an appointment with a skin specialist for me but by time it came around the bumps had disappeared again -_-

[[ PRETTY PRETTY PRETTY  *looks at hands*....Damn. ]]

Either way, today he decided that it's 'contact eczema'. Basically, my fingers flare up when they come into contact with something they aren't a fan of. The only thing I can think of that I use religiously (probably 2 - 3 times a week :S) is nail polish and nail polish remover. I constantly switch between skin products, makeup and  shower products, so I doubt it's any of those.

So my questions are - what exactly could my skin be reacting to? Chemical nasties? 'The big three'? And are there any nail polishes/ removers which are mainly made from natural ingredients?

 I'd really appreciate any help - I don't want to have to give up polishes, I'm an addict! And just to prove it, after going to the doctors I went and bought four polishes to cheer myself up.
